Description

The erecting tools of central processing unit heat radiator

The utility model relates to a kind of erecting tools of central processing unit heat radiator, relates in particular to a kind of instrument that is used in conjunction with central processing unit and heat radiator.The utility model utilizes mechanical realization to replace the fastening work that traditional manual fitting mode is finished CPU and heat radiator.

Central processing unit (CPU) is a main element indispensable in the computer system.Be mainly used to do sums, logical operation, explain the meaning of each instruction, and most element in the control computer system.

Because the development of technology, the execution speed of CPU is more and more faster.Therefore, CPU must possess good thermal diffusivity, just is unlikely overheated because of long-time running, causes usefulness to reduce, even influences the serviceable life of itself.The general practice is, directly sets firmly a fan on CPU, or at the heating face of CPU, the metal fin of fitting.Because heat radiator is made with the good material of conduction, thus it is directly contacted with the CPU surface, the thermal energy transfer that CPU sends is extremely outside, thus CPU is maintained between certain temperature range, keep its normal operation.

Because heat radiator is the another kind of structure that is attached on the CPU, so for fixing, it is bonding once to use adhesive to carry out.But the heat-conducting effect of glue material is relatively poor, and the heat energy that is difficult to CPU is sent passes to heat radiator effectively, thereby has a strong impact on radiating effect.In addition, the fusing point of colloid is lower, and is high when hot when running into, and can produce the thawing phenomenon, thereby cause heat radiator to keep good fixed relationship with CPU.

In addition, the mode that adopts fastener to fasten is also arranged, heat radiator is fixed on the CPU.Because fastener itself can not intercept heat radiator and do not contact with the surface of CPU, and fastener adopts metal or heat-resisting plastic cement to make usually, so better than gummed mode on effect.

Release since Intel Company after the box or cassette CPU of Pentium II series,,, reserve a plurality of perforation, use for heat radiator is fixing in the appropriate location of CPU so considered installing additional of heat radiator because execution speed is faster.As long as heat radiator is provided with perforation equally on correspondence position, can utilize fastener to pass corresponding perforation, heat radiator is fastened on the CPU.

Because the style of CPU is constantly weeded out the old and bring forth the new, cause the position of perforation to differ and decide.Must do the suitable change with CPU except the shape style of heat radiator, the position, hole also will be adjusted.Yet assembling operation in the past all is to lean on artificial treatment, and assembling person directly is pressed into fastener the Kong Weizhong of heat radiator and CPU correspondence with hand.Because assembling person's hand strength difference adds long continuous operation, can both be depressed into the predetermined degree of depth so can't guarantee each fastener, thereby the fixed effect after causing assembling differs, quality can't be consistent.In addition, assembling person continues to carry out the operation of pressing fastener, owing to pressure continues to concentrate on the specific region of hand, so also can cause hand to produce uncomfortable sensation.

In view of the above-mentioned problems, fundamental purpose of the present utility model is, at the assembly working of heat radiator and CPU, provides a kind of mechanical implement of special use, solves the variety of issue that in the past produced because of manual work.

The utility model provides a kind of erecting tools that does not need personnel directly to compress fastener.Operate very easyly, also can allow fastener all can arrive the identical fastening degree of depth simultaneously at every turn, keep the consistance of quality.

Relevant detailed description of the present utility model and technology contents, existing accompanying drawings is as follows:

Fig. 2 B is another side-looking action synoptic diagram of the present utility model, shows pressure head and is pressed in the second place on the fastener;

Fig. 3 is the enforcement illustration that the utility model is adjusted ram travel.

Referring now to Fig. 1.The figure shows a kind of erecting tools 1 that CPU is combined with heat radiator of being used in particular for.As shown in the figure, erecting tools 1 comprises: a bearing 10 is used to carry stacked CPU and heat radiator mutually; And a laminating mechanism 20, it is arranged at bearing 10 tops.Utilize this structure, CPU and heat radiator can be placed in the bearing 10 in advance, then, the fastener that will be placed in CPU and the corresponding perforation of heat radiator upper limb by laminating mechanism 20 in advance is pressed into and passes perforation, makes heat radiator and CPU be buckled into one (as described later in detail) each other.

Bearing 10 and laminating mechanism 20 are fixed on the board 30 simultaneously, perhaps interconnect with web member, allow the bearing 10 and the relative position of laminating mechanism 20 fix.Laminating mechanism 20 is high by upright 40 of a sway brace of being located on the board 30, and is positioned at the top of bearing 10.Laminating mechanism 20 comprises that a pedestal 41, is articulated in the feeding handle 42 of pedestal 41 lateral margins, and a shifting axle 43.Wherein, shifting axle 43 converts feeding handle 42 to the axial displacement action with respect to the rotary power that pedestal 41 pivots are produced.Shifting axle 43 belows are provided with a pressure head 44 that is positioned at bearing 10 tops just, and pressure head 44 can be done upper and lower displacement with shifting axle 43.

Shown in Fig. 2 A, 2B, according to structure described in the utility model, the operator can be stacked in CPU 50, heat radiator 51 and fastener 52 on the bearing 10 earlier in regular turn, rotates feeding handle 42 again by hand, orders about the related pressure head of shifting axle 43 44 to bottom offset.After fastener 52 upper limbs were run in pressure head 44 bottom surfaces, taking advantage of a situation applied downward strength to fastener 52 again, made fastener 52 vertically be pressed in the perforation of CPU 50 and heat radiator 51 correspondences.Bearing 10 is by pedestal 11, and is arranged on around the pedestal 11 and is higher than 12,13 compositions of a plurality of blocks of pedestal 11 upper surfaces.The space that

block

12,13 is enclosed can be set for, can hold the size of CPU 50 and heat radiator 51 just, so that CPU 50 and heat radiator 51 can both arrive ad-hoc location on the bearing 10 by the standardization role of

block

12,13 when operation each time.Like this, the corresponding aperture position of CPU 50 and heat radiator 51 remains on the same axis.When pressure head 44 was depressed, fastener 52 can successfully enter corresponding position, hole.In addition, in order to ensure when pressure head 44 is depressed, fastener 52 can buckle into perforation along correct mobile route, and the utility model is provided with a locating slot 45 at pressure head 44 lower edges, when pressure head 44 lower edge pressing fasteners 52, locating slot 45 contact jaws lucky and fastener 52 upper limbs are chimeric.Like this, fastener 52 is by chimeric with locating slot 45, keeps moving vertically downward.
